1 (The nose and mouth make up the first part where air enters your body. 2  The trachea, or windpipe, is the second part and it delivers air to the lungs. 3  Your lungs are the third part where oxygen is absorbed by the blood, which brings it to the rest of the body. 4  Finally, the diaphragm is the fourth part.
When you breathe in fresh air, it moves into the air sacs, where oxygen is absorbed into the blood stream and carried to all parts of your body. The air sacs also remove carbon dioxide from the blood. When you breathe out, stale air with carbon dioxide passes out of your airways and lungs.
